I love the comparison of string length of the same UTF-8 string in four programming languages (only the last one is correct, by the way):
Python 3:
len(“🤦🏼♂️”)
5
JavaScript / Java / C#:
“🤦🏼♂️”.length
7
Rust:
println!(“{}”, “🤦🏼♂️”.len());
17
Swift:
print(“🤦🏼♂️”.count)
1
That depends on your definition of correct lmao. Rust explicitly counts utf-8 scalar values, because that’s the length of the raw bytes contained in the string. There are many times where that value is more useful than the grapheme count.
